Abstract

331 primary school students studying from Nursery classes to Class IV in 2 randomly selected schools in Naxalbari Village in Darjeeling district of West Bengal were tested for visual acuity (VA), Vitamin A deficiency (VAD) and Bitot's spot. 329 students could be tested for visual acuity whereas all 331 students were tested for VAD and Bitot's spot. The prevalence of abnormal Visual Acuity (VA) (VA < 6/9 in any eye) in this study group was 3.65% and it was highest in 7-8 years age group in both the sexes contributing to 75% of the total students having abnormal VA. All these children fell within 50th percentile of weight and height for their respective age and sex. Hindu & ST children accounted for 91.67% & 50% abnormal VA respectively; however, when presence of abnormal VA was compared with its absence between 2 sexes, Hindu and Muslim students and in different castes, no statistically significant differences were found (p > .05). Students of Class-I and Class-II contributed 25% and 50% respectively and together accounted for 75% of abnormal VA. Prevalence of VAD was 8.16%. Among sufferers of VAD Hindus (81.48%) and ST (51.85%) were the main contributors; the differences between presence and absence of VAD in 2 sexes, among 3 religious groups were not statistically significant (p > .05); however, differences among ST and NonSCST groups, and again SC, ST and Non-SCST groups were statistically significant (p < .05). Prevalence of Bitot's spot was 3.63%. Among the students having Bitot's spot, females (58.33%) outnumber the males (41.67%); but the difference between presence and absence of Bitot's spot in 2 sexes was not statistically significant (p > .05). 83.33% each of Hindus and STs had Bitot's spot. No SC and no Muslim student had this spot; the differences between presence and absence of Bitot's spot between Hindu and Christian students were statistically significant (p < .01); similarly when the findings were considered between ST and NonSCST students the difference was found to be statistically highly significant (p < .001).

摘要

在西孟加拉邦大吉岭地区纳萨尔巴里村随机选取的2所学校中，对331名从幼儿园到四年级的小学生进行了视力、维生素A缺乏症（VAD）和毕脱斑检测。329名学生接受了视力检测，而所有331名学生都接受了VAD和毕脱斑检测。该研究组中视力异常（任何一只眼睛视力<6/9）的患病率为3.65%，在7至8岁年龄组中男女患病率最高，占视力异常学生总数的75%。所有这些儿童的体重和身高均处于各自年龄和性别的第50百分位数。印度教和在册部落（ST）儿童的视力异常率分别为91.67%和50%；然而，当比较视力异常与正常情况在不同性别、印度教和穆斯林学生以及不同种姓之间的差异时，未发现统计学上的显著差异（p>.05）。一年级和二年级学生的视力异常率分别为25%和50%，两者合计占视力异常总数的75%。VAD的患病率为8.16%。在VAD患者中，印度教徒（81.48%）和在册部落（51.85%）是主要患病群体；VAD在不同性别、三个宗教群体中的患病与否差异无统计学意义（p>.05）；然而，在册部落与非在册部落群体之间以及在册种姓、在册部落与非在册种姓群体之间的差异具有统计学意义（p<.05）。毕脱斑的患病率为3.63%。在有毕脱斑的学生中，女性（58.33%）多于男性（41.67%）；但毕脱斑在不同性别中的患病与否差异无统计学意义（p>.05）。印度教徒和在册部落学生中有毕脱斑的比例均为83.33%。没有在册种姓学生和穆斯林学生有此症状；印度教和基督教学生之间毕脱斑患病与否的差异具有统计学意义（p<.01）；同样，在册部落与非在册部落学生之间的差异具有高度统计学意义（p<.001）。
